WAL-DON United States Patent 3,377,633 MEANS FOR MOUNTING TOILET SEAT AND LID HINGE POST Vernon L. Walden, Crawfordsville, Ind., assignor to Ingress Manufacturing Co., Inc., Crawfordsville, Ind., a corporation of Indiana Filed Apr. 1, 1965, Ser. No. 444,581 1 Claim. (Cl. 4236) ABSTRACT OF THE DISCLOSURE A bracket means for mounting a hinge bracket on a toi et bowl consisting of a mounting bracket means which extends laterally across the rear portion of a toilet bowl and carries at each end an upraised ear or boss which is adapted to hingedly carry the toilet lid and seat, with the screwhead or nut being concealed.

This invention relates to toilet lid and seat mountings, and to hinge-providing means useful in installations and applications such as toilet mountings where members are required to be hingedly connected.

Toilets are usually installed along a wall, and often in a corner or adjacent a tub. Such a location, plus the relatively low height of the upper bowl flange off the floor, renders quite inconvenient and awkward an installation requiring the installer to install or tighten connectors from the underside. Yet connection means having a bracket which is connected or tightened from the underside have been used to avoid an upperside visibility of a connector bolt or nut. Toilets also pose the requirement of both the lid and seat to pivot about the same axis, to avoid rubbing or squeaking of those members as they are swung; and the hinge means has to provide that coaxial pivoting yet avoid unsightliness.

Concepts of the present invention, accordingly, provide a novel mounting of a toilet lid and seat, and a novel and economical means for concealed attachment thereof to a toiet bowl whereby the installation is substantially wholly from the upper side, thus providing ease of assembly, yet with no visible screwhead or nut.

These and other details, concepts, and advantages of the present invention will further appear in the following detailed description of illustrative embodiments thereof, taken in conjunction with the accompanying somewhat diagrammatic drawings, in which:

FIG. 1 is a top view of a toilet seat embodying the invention;

FIG. 2 is a side elevational view thereof;

FIG. 3 is a vertical cross-sectional view, taken generally along section line 3-3 of FIG. 2, illustrating details of the hinge construction;

FIG. 4 is a pictorial view of the end-portion of the mounting bracket, viewed from an outside rear viewing point;

FIG. 5 is a cross-sectional view of the mounting bracket, taken generally along section line 5-5 of FIG. 4, portions thereof being broken away to illustrate details of the mounting bolt means;

FIG. 6 is a pictorial view of cording to another embodiment;

FIG. 7 is a cross-sectional view, taken generally along section line 7-7 of FIG. 6, illustrating the mounting of the bracket of FIG. 6 onto an associated toilet bowl;

FIG. 8 is a detail View similar to FIG. 7, but illustrating a modified bracket and screw-concealing means; and

FIG. 9 is a cross-sectional view, similar to FIG. 3, but illustrating the hinge construction utilizing the mounting bracket of FIG. 6.

As illustrated in the drawings, a toilet seat construction a mounting bracket acice according to the first embodiment generally comprist a cover lid panel 10, a seat panel 12, and a mountin bracket 14 for hingedly connecting the lid 10 and seat 1 to a toilet bowl 16.

According to concepts of the invention, the mountin bracket 14 is adapted to be mounted from the upper sidt providing convenience and case of installation and It moval, yet with no visible bolt head or nut.

Providing this upper-side mounting, the mountin bracket 14 includes a central portion 18 which extend laterally across the rear of the toilet bowl 16, and carrie adjacent each end an upraised ear or boss 20 which, a yet to be explained, hingedly carries the lid 10 and sea 12; and the bracket 14 is shown provided in the region 0 each boss 20 with an opening 22 which registers with a1 opening 24 provided in a flange of the toilet bowl 16, to a mounting bolt 28. The upper portion of each boss 20 i provided with a counterbore 29 in line with the openin, 22, the bottom surface of which provides a seat for th downwardly facing surface of the bolt head 30; and th bolt head 30 is thus recessed into the counterbore 29 A cover 32, whose upper surface is contoured in accord ance with the contour of the adjacent portion of the bos; 20, is then slipped into the counterbore recess 29, con cealing the bolt head 30.

Prior to installing the cover 32, the upper-side mountin; is made tight by the installer holding a nut 34 below thr bowl flange and in registry with bowl-opening 24, as th bolt 28 is begun to be turned. The nut 34 is shown at having a washer 36 carried on its upper surface, and ar arm 38 carried by its lower surface. Frictional engagement of the bolt 28 and the threads of nut 34, as the bolt 28 is turned, moves the nut arm 38 into abutment with at associated wall or bead of the toilet bowl 16; and this abutting contact holds the nut 34 against further turning as the bolt 28 is turned in tightening. Thus, the installation, except for obtaining the initial registry of nut 34 with bolt 28, is entirely from the upper side, and no wrench or other tool is needed to be applied to the nut.

Other concepts of the invention provide novel hinge means for the cover 10 and lid 12, as are now to be explained.

The rear of the toilet lid 10 is shown as provided at each, side, just laterally inwardly of the bracket-boss 20, with a downwardly-extending flange 40; and the rear of the seat 12 is shown provided, at a spacing such that they are laterally inwardly of lid flanges 40, with rearwardlyextending flanges 42. The adjacent surfaces of each flange 40 and 42 are shown provided with complementary semispher-ical recesses 44- and 46, respectively; and a ball 48 is provided, which, when the lid 10 and seat 12 are assembled by resilient deformation of flanges 40 and/ or 42 to permit them to mutually receive the ball 48, hingedly interconnects the lid 10 and seat 12 in a concealed manner.

Similarly, the adjacent surfaces of each bracket boss 20 and lid-flange 40, are shown provided with complementary semi-spherical recesses 50 and 52, respectively; and a ball 54 is provided which, when the lid 10 and bracket 14 are assembled by resilient deformation of bracket-boss 20 and/or lid-flange 40 to permit them to mutually receive the ball 54, hingedly interconnects the lid 10 to the bracket 14 and thus to the toilet bowl 16, in a concealed manner.

FIG. 6 illustrates another embodiment, wherein there are provided two laterally-spaced mounting brackets (rather than the single bracket 14 with spaced bosses as in the first embodiment), each having, on each side of an upraised ear or boss 62, an integral semi-spherical protrusion 64. The two protrusions 64 of each bracket 60 form in effect a ball-shaped hinge-pin by means now described.

The toilet lid 10a (FIG. 9) has spaced downwardlytending flanges 40a, the inner surface of each being proded with a semi-spherical recess 52a; and the spacing of e flanges 40a is such that resilient deformation must be iparted to the bracket-boss 62 and/ or the lid-flange 40a permit the lid a to be assembled onto the brackets with each recess 52a fitted over the associated protruon 64. With the lid 10a and brackets 60 assembled, the arts provide a concealed hinge connection of the lid 10a the brackets 60 and thus also to the toilet bowl 16.

Similarly, the toilet seat 12a has spaced rearwardlyitending flanges 42a, the outer surface of each being 'ovided with a semi-spherical recess 46a; and the spac- 1g of the flanges 42a is such that resilient deformation rust be imparted to the bracket-boss 62 and/or the seatange 42a to permit the seat 12a to be assembled onto 1e brackets 60, with each recess 46a fitted over the assoated protrusion 64. With the seat 12a and brackets 60 ssembled, the parts provide a concealed hinge connecon of the seat 12a to the brackets 60 and thus also to the rile t bowl 16.

FIG. 7 illustrates means providing upper-side mountrg yet with no visible screwhead or nut, for the embodirent of FIG. 6, generally in accordance with the first emodiment, the similarity being indicated by correspondncy of reference numerals. However, in contrast to the rst embodiment, in which the screw-hole 22 and coun- :rbore 29 are located in a region of the upstanding boss 0, in the FIG. 6 embodiment the screwhole 22 is located 1 the region of a flat flange 65 of the bracket 60; thus 1e cover 32 is of a simpler shape, having a horizontal 5p surface, yet it substantially is flush with adjacent porlons of the bracket.

FIG. 8 illustrates modified screw-concealing means in lhiCh the upper end of the bracket-recess 29 is provided vith an upraised rim 66, and a cover 32a fits over the ecess 29 and rim 66, concealing the screw head 30; and he rim 66 provides both a fitting seat for the cover 32a tnd a rim preventing the draining of liquid into the brackt-recess 29.

It is thus seen that either embodiment of the invention Jrovides a mounting means of new and advantageous con- :epts, having features and advantages of ease and converience of concealed mounting from the upper side, and :oncealment of the connector bolt and of the screw head.

It will thus be seen from the foregoing description of he invention according to the illustrative embodiments, :onsidered with the accompanying drawings and claim, hat the invention provides a novel and advantageous nounting means having desirable characteristics and ac- :omplishing its intended objects, including those herein- 4 before pointed out and others which are inherent in the invention.

It will be understood that modifications and variations may be effected without departing from the scope of the novel concepts of the present invention; accordingly the invention is not to be considered limited to the specific form or arrangement herein described and shown.
